    Abstract To adsorb and separate platinum-group metals efficiently from simulated high-level liquid waste, two adsorbents, N,N,N′,N′-tetra-n-hexyl-3,6-dithiaoctane-1,8-diamide (THDTODA)/SiO2-P and (THDTODA + dodecanol)/SiO2-P, were prepared by impregnation of THDTODA with or without dodecanol into macroporous silica/styrene–divinylbenzene copolymer composite particles SiO2-P. The effect of the addition of dodecanol to THDTODA fixed silica-based adsorbents on the separation of platinum-group metals and other metals was evaluated by batch adsorption and chromatographic separation experiments. THDTODA/SiO2-P adsorbed Ru(III) and Rh(III) more than (THDTODA + dodecanol)/SiO2-P did in concentrated HNO3 solution. From the calculated thermodynamic parameters, dodecanol was considered to have little effect on the temperature dependence of the adsorptions of Ru(III), Zr(IV), Mo(VI), and Re(VII) onto the THDTODA adsorbents. Furthermore, in the results of column chromatography experiments, the effects of dodecanol addition on the separation properties were observed for Ru(III), Zr(IV), and Mo(VI), but little effect was observed for Pd(II) and Re(VII).

    The redox behavior of chromium was investigated under three conditions for the nitric acid solutions considering the operating conditions of the reprocessing plant -atmospheric-pressure boiling, reduced-pressure boiling, and atmospheric-pressure non-boiling-to determine the relationship between the corrosion of austenitic stainless steel (R-SUS304ULC) and this behavior. The oxidation of Cr(III) to Cr(VI) in 8 M boiling nitric acid was increased over that in non-boiling nitric acid, even at the same temperature by measuring the time dependence of the chromium concentration and thermodynamic calculations. These results show that Cr(III) is more likely to oxidize under boiling than non-boiling conditions. On the other hand, the apparent rate of Cr(VI) reduction, as consumed by corrosion of the stainless steel, was more than 10 times greater than the rate of Cr(III) oxidation in 8 M nitric acid solution. This is evidence that the rate of Cr(VI) reduction by corrosion is kinetically faster than the rate of Cr(III) oxidation. In addition, the apparent rate of Cr(VI) reduction and the corrosion rate of R-SUS304ULC were positively correlated. Therefore, these indicate that the corrosion of R-SUS304ULC apparently follows Arrhenius' law in 8 M nitric acid solution containing Cr(VI), regardless of the boiling or non-boiling conditions.

    The Fukushima Daiichi nuclear power plant accident caused radioactive pollution by 131I, 134Cs and 137Cs. The surface of the ground was contaminated at a volume of 3 × 107 m3. The government has mandated that the top 5 cm of the contaminated soil be removed and stored, in this way, it is desirable to reduce its volume. Soil samples were collected from a mountain, a rice field and a vegetable field in northern Japan, and the silt was extracted from the muddy water by washing the soil. Next, the silt was sprayed with a solution of cesium carbonate (Cs2CO3). We determined the amounts of Al, Si, K and Cs in the silt particles using micro-particle-induced X-ray emission (micro-PIXE) analysis. The silt particles from a vegetable field, a rice field and a mountain were mainly formed from smectite or vermiculite, which absorbs Cs atoms. The measurements at multiple detection angles confirmed that Cs atoms were uniformly absorbed within silt particles less than [Formula: see text] in diameter. This resulted that the radioactive Cs atoms were adsorbed in silt particles within [Formula: see text] of the surface.

    Tc extraction and separation experiments were performed basing on PUREX technique with using spent UO2 fuel with burn-up of 44 GWd t-1. The experimental results were examined with performing calculations by a simulation code ESSCAR (Extraction System Simulation Code for Advanced Reprocessing). It was demonstrated that Tc can be extracted almost quantitatively from a dissolver solution and that extracted Tc also can be recovered almost quantitatively by scrubbing. Further, it is clearly presented with the calculation results of ESSCAR that Tc extraction mechanism is dominated by the synergistic effect of Zr and U.

    More details Close

    Electrolytic reduction of Tc (VII) in a nitric acid solution was examined to recover Tc as well as rare metals (Pd, Ru, and Rh) by an electrolytic extraction method, i. e. electro-reductive deposition, from a spent fuel solution for future nuclear fuel reprocessing. An absorption peak at 482 nm observed after electrolytic reduction of Tc (VII) in 3 M HNO3 at -0.3 and -1.0V vs SSE (standard silver electrode) suggests the reduction of Tc (VII) to Tc (IV). When Pd is present together with Tc in 1 M HNO3, the concentration of Tc decreased to 85% of the initial concentration by electrolysis at ±0.0 V vs. SSE for 60 min, suggesting acceleration of Tc deposition by Pd (promoter effect). The Tc concentration, however, increased returning to the initial value after further electrolysis. The Pd deposit from Tc-Pd-Ru-Rh solution redissolved more easily than that from Pd-Ru-Rh, as a consequence of a change in the oxidation-reduction property of the Pd deposit due to the presence of Tc in the solution.

    Ruthenium, one of the useful elements contained in high-level liquid waste (HLLW), was expected to be converted into resource by separation and recovery. On the other hand, ruthenium complexes were important materials as dye for dye-sensitized solar cell. In this study, a new separation and recovery process of ruthenium from HLLW constructed by using novel sulfur-containing diamide and hydroxyl oxime extractant-impregnated macroporous silica-based adsorbents. In addition, an available dye for dye-sensitized solar cell was synthesized from the recovered ruthenium. These results indicated the possibility of effective reuse of HLLW for energy generation.

    Development of X-ray detectors using a compound semiconductor, thallium bromide (TlBr), was performed for realizing high-sensitive flat-panel detectors. High-pure TlBr was obtained by the horizontal zone purification method. Small pixel electrodes were formed successfully on TlBr single crystals. Thin-film detectors were fabricated from TlBr thin films deposited on ITO glass substrates by the vacuum evaporation method. The fabricated thin films exhibited high resistivity at room temperature.

    Srに高選択性のDtBuCH18C6(di-t-butylcyclohexano-18-crown-6)化合物抽出剤をスチレン・ジビニルベンゼンポリマーを被覆した多孔性シリカ担体粒子(SiO_2-P)に含浸担持してDtBuCH18C6/SiO_2-P吸着材を創製した。吸着材の基本特性は、フーリエ変換赤外分光分析及び示差熱・熱重量分析により、その表面構造や重量組成・熱分解特性を測定評価した。 DtBuCH18C6/SiO_2-P吸着材はSEM観察により良好な調製が確認され、粒径は50□m程度であった。耐熱性に関してはSiO_2-P担体には見られないピーク(約160～180℃)が得られたのでDtBuCH18C6の分解であると推定される。SiO_2-P、抽出剤、改質剤の熱重量減少が仕込み量とよく一致した DtBuCH18C6/SiO_2-P吸着材を用いて、硝酸溶液中における代表的なFP元素 (Cs, Sr, La, Nd, Sm, Gd, Zr, Mo, 白金族)の吸着試験を行うとともに、カラムに充填して抽出クロマトグラフ法による分離試験を検討した。 吸着材にSrのみの収着を確認した。また、2～3M硝酸で高い吸着性(分配係数は約180cm^3/g)を示した。Srに対する分配係数は温度の増加と共に低下した。Sr吸着量は平衡濃度60mM付近で平衡に達した(平衡吸着量:約0.30mmol/g)。また、Srの吸着はおおかたLangmuir型であるとわかった。EPMA分析によりSrはDtBuCH18C6/SiO_2-Pの内部まで収着したことを確認できた。 次に、破過試験において、線流速を小さくすると5%破過が増加した(0.64cm/minで全吸着容量0.26mmol/g)。破過試験回数によって吸着材カラムの劣化が見られた。充填したSr吸着材の量に対する通液した溶液量を考慮して評価する必要がある。全収着量を溶離するために、約38.2BVの溶離液が必要であった。また、Sr・Baとその他FP元素を分離することができた。
